Condition
monitoring specialists SENSONICS have introduced the Sentry G3
machinery protection monitor, a high performance signal conditioning
unit. The new G3 monitor builds upon the established range of
Sentry protection systems developed by Sensonics and is designed
to be the most flexible and feature rich Turbine Supervisory
System available. It provides a universal platform for the interfacing
of various sensor types in compliance with the API 670 standard.

Each of the units
four channels can be independently programmed to provide continuous
monitoring and protection across a broad spectrum of measurement
regimes, including vibration, expansion, temperature and speed.
Sentry G3 utilises the latest DSP technology, so once a channel
is set up and running, the resulting alarm relay and analogue
output facilities are independent from the remaining module functionality,
ensuring a scalable, high integrity configuration.

The unit has
an integral intuitive colour LCD display and drive facility which
provides immediate viewing and access to the machines parameters.
Several modes of display are available to suit specific applications,
such as an alarm historian and parameter trending per channel.
It also provides the necessary power source for the selected
transducer, providing for 2 (ICP type) or 3 wire accelerometer
variants, ± 24V proximity probe systems, LVDTs and
a range of speed and temperature sensors. Each transducer signal
is buffered and available via the front panel analogue connection
arrangement while a USB interface is provided for programming
the unit and for storage of channel history and settings.

The G3 system
offers excellent channel density with up to 24 measurement channels
in a 3U format, also each channel can provide independent analogue
outputs of current and voltage for DCS connection, in addition
to an alarm relay. Further alarm relay expansion is possible
through connection to digital outputs at the rear of the module.

The system is
designed for mounting in a custom 19 rack assembly which
also contains a dual redundant power supply option.

Sentry G3 provides
state-of-the-art protection for the following modes:
